Same thing happened to my passenger-side corner light during the drive from the hotel to 4ngiefest this year. I had to leave a cloth draped over the corner light so nobody would see.

I bought Khoalty, but they didn't slide in all the way to clip in, but they sit flush. Also... there are cracks starting to appear around the edges... like the seals are cracking. I don't know. It's weird. From five feet away, you can't tell, though. I'm going smoked the next time around.
